GRAIN-HEATER CONTROLLER.

Specification of Letters Patent.

Patented Nov. 2, 1915.

2' '0 all whom it may concern:

Be it known that I, ALLEN C. BRANTING- HAM, a citizen of the United States, residing at Toledo, Lucas county, Ohio, have invented a new and useful Grain-Heater Controller, of which the following is a specification.

This invention relates to devices for uniformly treating material.

This invention has utility when embodied in grain heaters having a plurality of ways.

Referring to the drawings: Figure 1 is a' side elevation with parts broken away showing an embodiment of the invention in a grain heater; Fig. 2 is a plan view thereof with parts broken away to show the various features thereof; Fig. 3 is a detail view on an enlarged scale showing a tilting hopper and the driver therefor; Fig. 4 is a detail view in side elevation of the driving link; Fig. 5 is a side elevation of one of the hoppers; and Fig. 6 is a bottom plan view thereof.

The material to be treated is received in the upper delivery device 1 forming a receiving chamber or hopper with openings 2 therethrough from which the material may directly flow into the tubes or parallel ways 3 of the grain heater. These tubes 3 are mounted in the heads 4, 5, carried by the cylindrical drum 6 of the heater, said heater having the insulating jacket 7. The heat medium is supplied by means of the intake pipe 8 and is discharged therefrom through the duct 9, which may be condensed steam when steam is used as the heating medium.

Carried by the outer shell of the insulating jacket are brackets 11 upon which may rest springs 12 abutting against nuts 13 as the springs and nuts surround the rods 14 adjustably connected to yieldably poise the delivery device 1. As there is an accumulation of material in the delivery device 1, the springs 12 are compressed and in this settling down of the rods 14:, the platform 15 is also carried downward and farther away from the ways 3. This platform 15 has slats 16 and intermediate slots 17. The slats 16 are normally in alinement with the ways 3 so that the grain tumbling about the chain 18 in its passage through the heating ways 3 may have its through travel checked or impeded when it strikes the slat 16. Upon the settling of the platform 15 due to accu mulation of grain in the delivery hopper 1, greater space between the ways 3 and the slats 16 permits a greater rate of flow of material through said ways and accordingly this automatic adjustment to care for material flow is an automatic means for varymg the treating rate by varying the flow through the ways 3. The material passing through the slots 17 in the platform 15 is collected by the hopper 19 for a common discharge. Said hopper 19 is suspended from the heater proper by the brackets 19. As an additional effective flow. checking or varying means, a continuous drive device is adopted. The pulley 20 is continuously driven from the source of power to rotate the shaft 21 on which said pulley is mounted. Said shaft 21 is carried by brackets 22, 23 mounted on the heater. The shaft 21 has the crank wheel 24 carrying the wrist pin 25. This wrist pin 25 has the block 26 reciprocable in the slot 27 in the rotation of the shaft 21 and effective to drive the link 28 as loosely suspended by the links 29 carried by the brackets 30 mounted in the lower diaphragm 5 of the heater. This link 28 has notches 31 therein which engage pins 32 of the material deflectors or oscillating hoppers 33 having their pivot pins 34% mounted in brackets 35 attached to the lower heater diaphragm 5. These hoppers 33 may have divisions 36 therein as separate compartments for the different ways or tubes 3 in registry therewith.

In operation material received in the member 1 will flow therethrough and be distributed and pass through the several ways 3 of the heater for uniform treatment. The diffigulty to overcome is excessive flow through certain of the ways with a relatively retarded flow through others which may result in excessive heating or treatment of the slow flowing material and insufficient treatment of the more rapid flow. In the device as disclosed there is provision made for checking material flow, thereby insuring intermittent greater velocity flow rate or such checking control that high momentum is avoided. Congestion of material in the receiving hopper 1 will weigh down this hopper to move the platform 15 away from the lower ends of the tubes 3 and thus according a larger clearance between the ends of the ways 3 and the slats 16 of the platform 15 permitting a greater flow rate to catch up with the contents of the hopper 1. This is desirable, as in practice these heat- =the platform, thereby means for oscillating said deflector.

ers may thn be placed in a mill to care for a stream of material as demanded by the circuit icilow ii ig or as cared various machines preceding the heater. While the heating may be adjusted by heating medium supply, adjustments may"bemad'e asi ihefl w eby- ,adi
